Doyle Raizner represents U.S. National Guardsmen and members of the British Royal Air Force who suffered injuries due to their exposure to sodium dicromate in Iraq. The documents were uncovered as part of discovery in the lawsuit after KBR had continued to deny that they were aware of the potentially toxic chemicals until soldiers became ill. The U.S. Department of Defense cited KBR in a September 2011 report for, among other things, failing to act quickly in warning or protecting soldiers and civilians from exposure to sodium dicromate.
